HARROW AND ROLLER.

SPECIFICATION forming part of Letters Patent No. 500,064, dated June 20,1893.

Application filed February 16, 1893. Serial No. 462,580- (No model.) I

To all whom itmay concern.-

Be it known that I, FRANCIS B. HARVEY, a

citizen of the United States of America, re-

Rollers; and I do hereby declare the following to be afull,clear,andexact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

This invention relates to improvements in combined harrows and rollers,and is designed more especially as an improvement upon my patent datedApril 26, 1892, No 473,746.

In the accompanying drawings, Figure 1 is a perspective View of a harrowand roller constructed in accordance with my invention, and Fig. 2 is adetail view.

The object of the present invention is to provide means whereby theharrow section can be raised and lowered by the driver while occupyingthe seat or while walking behind the machine. I

A designates the main frame of the machine, which is provided withrollers and is constructed substantially as shown in the patent referredto. The cross-bar A of the 4 frame is provided with uprights a and a,

which are preferably made from a single flat bar of iron the upper endsbeing perforated while the lower ends are bent at right angles andsecured to the crossbar A by means of bolts or other suitable fasteningdevices.

The seat, (J, is supported by bars which extend under the same andarebent down to bear upon the cross-bars A and A of the main frame, andthese supporting bars may be suitably braced to support the seat rigidlyupon the main frame.

The harrow section, D, is provided with spring teeth B, or spring barsto which teeth may be attached which are placed in reverse position tothat usually occupied by spring teeth, as shownin the drawings, wherebyseveral advantages are gained, such as greater durability in retainingtheir set, a shorter bar and less motion in clearing the teeth attachedthereto from rubbish. To these spring bars '13 are attached teeth of anyapproved construction, preferably such as are shown in my applicationfiled October 14, 1892, and pend- :ing concurrently herewith. To therear crossbar of the barrow section isconnected a lever I, by means of astaple b, said lever being curved upward rear of the harro W section soas to clear the rear roller, and this lever, adjacent to the standard orupright a, is givena turn or twist, and the lower end is slotted forengagement with the standard, to which it is secured by a U-bolt, asshown in Fig. 2, said bolt being preferably made of a single rod ofmetal and provided adjacent to its terminals with a fiat spring 0. Thespring 0 can be turned to lie on a line with one of the members of thebolt, and when in such position the members of the bolt are passedthrough two of the perforations in the standard. The end of the leverlying between the members of the bolt will then he held in positionagainst movement. A similarbolt is used to connect the harrow sectionwith the standards or uprights a.

The-lever I is provided with parallel perforated bars or plates 4. iwhich are "connected to eachother at their upper ends and at their lowerends are pivoted to the lever I by a suitable connecting bolt, and withthese bars or engages, said hand-lever being bent as shown and securedto the rear portion of the seat 0 by hangers or straps k and 7t','thehanger or strap It being provided with a laterally proj ecting portion10 which projects beyond the side of the seat and engages with the leverK to prevent excessive rearward movement thereof.

L designates a catch-bar which is attached to one side of the seat C andis held in place by suitable straps having bent ends. This bar carries atriangular plate Z which is adapted to engage with the lever K so as tohold said lever rigid, and thus prevent a rearward movement of theharrow. The ends of the bar L are bent as shown, so that the catchplatewill be retained normally in a horizontal position by gravity. The frontend of the bar L lies adjacent to the front of the seat while the rearend is extended to be readily plates the projecting end of a hand-leverK v his knee.

grasped by the driver when walking, for the purpose of turning itsufficiently to allow the vertical leverK to pass the catch-plate, whenthe harrow can be raised by the lever I.

It will be noted that by the construction herein shown the h arrowsection can be raised by the driver operating the vertical lever L whenriding or the horizontal lever I when walking. The front end of the barL can be operated by the drivers hand to throw the plate or catch Z outof engagement with the lever K, or it may be turned in its hearing by Bymeans of theselevers and the U-bolts inthe perforated standards a a Iprovide for the rigid holding of the teeth in the 'harrow frame at thedesired depth; but when it is desired to let the harrow run freely inthe ground I place the U-bolts in the two per forations in the top ofthe standards act/"and allow the bar connecting the harrow frame withsaid standards to play between the bolts and the harrow bar A at thesame time withdrawing the bolt that connects the plates it and theleverI and place the bolt through the plates and under the-lever,leaving the lever free between the plates and the bolt below and theend-of the vertical lever K above. Thus I'give the rear of the harrowthe same play between the plates that it has in front under the U bolts,allowing it to run freely.

When it is desired to hold the harrow section clear of the ground a hookM carried by the rear portion of the drivers seat can be caused toengage with the rear portion of the hand-lever K and thus hold thesection raised. The depth which the harrow teeth will enter the groundmay be regulated by adjusting the connecting bars to the standards a anda, and by correspondingly changing the position of lever I in the platesv. i, so as to bring the rear end of the harrow on the same level as thefront end.

I am aware that prior to my invention it has been proposed to provide aclod-crusher with a harrow section which is hinged between the rollersand is provided with a lever which is connected to the rear portion ofthe harrow frame and extends forwardly so that the harrow can be raisedto free the same from debris, and such construction I do not claimbroadly; but

What I claim as new, and desire to secure by Letters Patent, is-

1. In a harrow and roller, a seat suitably supported upon-the main frameand provided with a catch-bar which is adapted to engage' with ahand-lever also supported by the seat, said lever being connected to arearwardly extending bar I, which isattached to the harrow section andto the main frame, substantially as shown, and for the purpose setforth.

2. In combination with a harrow and roller frame constructedsubstantially as shown and having uprights with perforations, barsconnecting a harrow section thereto, of U-bolts adapted to be passedthrough perforations in the standards or uprights and lie over the endsof the connecting bars, substantially as shown, and for the purpose setforth.

3. In combination with a harrow and roller frame constructedsubstantially as shown, a lever pivoted centrally thereon, said leverbeing provided at its forward end with members which embrace aperforated standard, said lever being attached to the rear portion ofthe harrow section and extending rearwardly beyond the rear roller,means for connecting the same with a hand-lever pivoted to thesupporting seat, and a gravity catch bar also-having a rearwardlyextended portion, substantially as shown, and for the purpose set forth.

4. In a harrow and roller, the combination, of a lever pivoted to theframe and connected to the harro w section, perforated plates 2'1;pivoted to the lever and connected to the rear end of a hand-lever Kwhich is attached to the seat by hangers 7c and is, one of said hangershaving a laterally projecting portion with which the lever engages, of agravity catch-bar also supported by the seat, said catch-bar having bentends, substantially as shown and for the purpose set forth.

In testimony whereof I aflix my signatu re in presence of-two witnesses.

FRANCIS B. HARVEY.
